Summary of: Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Climate Change
By: Naomi Oreskes


Embark on a journey uncovering the hidden truths behind pressing issues, as ‘Merchants of Doubt’ reveals how a select group of scientists deliberately obscured critical information about the consequences of smoking tobacco and the reality of climate change. This book summary dives into the diabolical partnership between the tobacco industry and dishonest scientists, who banded together to fight against emerging evidence, gradually turning their sights on issues including acid rain, the ozone layer, and global warming. Be prepared to challenge your own beliefs and gain insights into how political motivations and unscrupulous business practices have distorted crucial scientific knowledge.

Tobacco Industry’s Dirty Secret

The tobacco industry was well aware of the harmful effects of smoking as early as the 1950s but chose to mislead their customers by propagating doubt about the validity of scientifically proven facts. To save tobacco’s deteriorating image, they hired a PR firm to cast doubt upon the idea that smoking was bad for health. The tobacco companies even funded top universities and hired respected scientists to prove that smoking was not connected to health problems. However, they could only suppress the truth for so long, and eventually people wisened up.

Uncovering the Tobacco Industry’s War on Science

The tobacco industry fought to suppress the truth about the harmful effects of smoking. While scientific evidence emerged about the detrimental effects of smoking, the dangers of passive smoking were not recognized until the 1980s. The industry disputed claims by attacking science, including the EPA report on second-hand smoke’s risks, which had been peer-reviewed twice. Despite being proven wrong, the industry misled the public. This summary sheds light on how the tobacco industry’s campaign against scientific evidence unfolded.

The Fight Against Nuclear War

The fear of nuclear war led to the controversial Strategic Defense Initiative (SDI) in the 1980s. While 6,500 scientists opposed it, three conservative scientists, including Fred Seitz, founded the George C. Marshall Institute to promote propaganda about the Soviet threat and bolster the SDI. Although their ideas were scientifically invalid, they gained public attention using the Fairness Doctrine policy, prolonging the debate.

The Politics of Acid Rain

The book describes the emergence of acid rain as an environmental issue and the politics surrounding its treatment in the US.

The latter half of the twentieth century brought about a wave of environmental issues that garnered the attention of scientists and politicians alike. Among these challenges was acid rain, which had been exhaustively studied since the 1960s. Acid rain occurs when rainwater becomes acidic due to a lower than normal pH concentration. This phenomenon stunts forest and plant growth and can cause harm to aquatic life.

Research has shown that acid rain can be traced back to the use of fossil fuels, and that the pollution that leads to it may come from a different geographical location than where the rain falls. Despite ample scientific evidence, the US government neglected the issue throughout the 1970s, even as Canadian scientists found that 50% of acid rain in their country came from American emissions.

Finally, in 1980, both countries came together to form teams to research the problem. The findings were reviewed by the US National Academy of Sciences in 1981, but were subsequently reevaluated by a panel of independent scientists that was handpicked by the White House. Fred Singer, a panelist concerned primarily with the financial costs of any proposals to combat acid rain, was added to the group by the US government, even though he was not initially chosen by panel chairman William A. Nierenberg.

The final review was edited so heavily that the solutions presented seemed dubious at best, calling into question the scientific consensus on how to proceed. The book delves into the politics surrounding acid rain, revealing how the threat of action against pollution was quashed by governmental interference in science.
